Captive-Bred Matted Filefish (Aiptasia-Eating) (Acreichthys tomentosus) – Approx. 1–2”

Buy a Captive-Bred Matted Filefish (Acreichthys tomentosus) online from Reef Hacker. Also known as the Aiptasia-Eating Filefish, this unique species is highly valued by reef aquarists for its natural ability to control nuisance Aiptasia anemones in marine aquariums.

This captive-bred specimen is conditioned to accept prepared foods, including high-quality pellets and frozen diets, making it far easier to maintain than many wild-caught individuals. Its mottled camouflage coloration allows it to blend naturally into reef environments while it actively hunts small pests.

The Matted Filefish is an excellent utility fish for reef keepers battling Aiptasia outbreaks and can be a highly effective biological solution when introduced into established aquariums.

Each specimen is carefully inspected and confirmed feeding prior to shipment, ensuring you receive a healthy fish ready to adapt to aquarium life.
